Abstract: 462,331. Typewriters &c. WANDERER-WERKE VORM. WINKLHOFER & JAENICKE AKT.-GES. Sept. 9, 1935, No. 25050. Convention date, Sept. 7, 1934. [Class 100 (iv)] [Also in Group XIX] Column-printing arrangements.-A calculating-machine has a paper carriage provided with cams for controlling column-spacing movements of the carriage, the cams being located between the horizontally disposed tracks which guide the carriage. Line-spacing mechanism is also described. The carriage 10, Fig. 1, has rails 9 engaging balls 36 co-operating with fixed rails 8. The control cams are mounted in a frame 20, Fig. 15, detachably secured and located in the carriage 10 by screws 24 having pointed ends entering conical recesses in the frame. The cams are mounted on holders 28 which enter slots 27 in the frame 20. Some of the cams may have three operative points 42, 43, 44, Fig. 19. In another form, the cams are constituted by pins inserted in holes in a holder 84. An auxiliary holder 83 may be attached to the holder 84 and the cam pins 85 inserted in this auxiliary holder. The pins 85 are held in position by a plate which is fixed over the frame 20. During a machine operation a disc 64, Fig. 2, is rocked first clockwise and then anticlockwise. Pins 300, 301 on the disc engage slots in a member 304 and thereby support the member. When the disc turns clockwise, the member 304 passes beneath a pin 306 on a disc 307 and is then moved to the right by a spring 305. The disc 307 is geared to a sector 309 on a shaft 30 carrying a stop 31. The cam holders 28 are caused to engage this stop by a spring which pulls the carriage. During the return of the disc 64, the member 304 rocks the rod 30 to turn the stop 31 to release the carriage. When the lip 366 of the member 304 moves from beneath the pin 306 a spring on the shaft 30 restores the stop to active position to limit the carriage movement to one stop. One face of the stop is bevelled so that the carriage can move freely in the reverse direction. The machine is set for this by depressing a key 170, Fig. 6, which rocks clockwise a lever 179 to remove its end 187 from a pin 186 on a lever 188 which is then rocked by a spring 190. An arm 195 is thus moved into such a position that, upon the next rocking of the stop shaft 30 to release the carriage an arm 38 on this shaft is latched by the arm 195 and the stop 31 cannot limit the column spacing movement of the carriage. When the carriage reaches a certain position a cam 202 rocks a lever 196 to lift a link, 197 connected to a lever 198 which restores the arm 195 to stop the carriage movement. Line-spacing mechanism.-Two mechanisms are provided for this. One can operate at each machine operation when a single column is to be printed. An extension 315, Fig. 2, of the disc 64 rocks a yoke 316 actuating ratchet mechanism effecting line spacing. The other mechanism causes a spacing movement at the end of each line. A rack 252, Fig. 12, is engaged by a pinion 251 driven by power at the end of each line to restore the carriage. The rack has a small initial movement relative to the carriage, this movement being transmitted by a pinion 259 to a rod 260 which actuates the line-spacing mechanism. Carriage-returning mechanism.-When the carriage reaches a predetermined position, a cam 230, Fig. 9, depresses a lever 232 which lowers a link 235 to rock a latch 236 to release a slide 242 which is moved to the left by a spring 243. The slide rocks a shaft 247 which couples a motor to the carriage-returning gear 251, Fig. 12. When the slide 242, Fig. 9, moves to the left, a slot 267 in it engages a pin on a lever 269 connected bv a link 270 to an arm 271 which is thus brought into the path of another cam on the carriage. When this cam depresses the arm 271, the slide 242 is restored and the carriage arrested. The carriage return can be initiated by depressing a key which rocks a lever 264 to engage a pin on the latch 236. Another manual control comprises a key actuating a lever (not shown) which engages toggle levers 280, 281 connected to the lever 269. When the slide 242 is released (either by the carriage cam or by the key), the arm 271 is lifted higher than normally and is consequently depressed by another cam on the carriage to arrest the return movement of the carriage at a different columnar position.
